No, you're not alone. I'm not rebuying two exact same discs just to get an alleged remaster of one film. I find it very odd that, at this point, it hasn't even been determined if GBU is indeed a better transfer. Even if it's the better-received Italian print, the studio should just come clean...
There's an easy solution for those who don't want to buy a box set to get one film: import the UK release. I think the steelbook has been cancelled but there should still be a regular release coming. Making people spend good money on something they already own is a crappy thing to do.
